Thanks Lisa You can specify a regular expression to match that pattern via an <openended>'s /mask attribute. Alternatively, you can achieve a similar effect using /isvalidresponse and a couple of string functions: <openended myopended> / charlimit = 8 / isvalidresponse = [ length(replaceall(tolower(openended.myopended.response), "x","")) == 4 && length(replaceall(tolower(openended.myopended.response), "o","")) == 4 ] </openended>
